CREAM-COOLER.

Specification of Letters Patent.

Patented Sept. 30, 1913.

Application filed March 28, 1913. Serial No. 757,322.

Coolers, of which the following is a specification.

My invention relates to devices for cooling liquids and more particularly to that class of devices which are used in cooling milk or cream, and the primary object of my invention is to provide a cooler of the above type, which is adapted to receive the liquid in a heated or warm condition atone end and to pass the same over a series of retards, through which a current of cooling liquid is passed. 7

A further object of my invention is to provide a cooler of the type set forth, in which the liquid to be cooled and the cooling medium are circulated by gravity through the device, means being provided whereby the flow of the liquid to be cooled is regulated and the intermingling of the two liquids prevented.

Another object of my invention is to provide a cooler which extends in a horizontal plane, departing from the well known vertical type, which requires extensive lifting of the milk or cream to the cooler entrance chamber, the said cooler being elevated only a short. distance from the floor and at such a height, to permit of the milk or cream flowing from the separator exhaust nozzle, directly into the receiving chamber of the cooler.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed. r

The invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in which Figure 1 is a top plan view of my improved cream cooling device, Fig. 2 is a longitudinal section taken on line 0ca of Fig.

1, and Fig. 3 is a transverse section taken on line g z of Fig. 2.

Referring to the drawings wherein similar numerals of reference indicate like parts, 1 designates the body member or table, preferably constructed of sheet copper, which is supported at its opposite ends on legs 2 and 3, suitably secured at the respective corners of said table 1, the legs 2 at the upper end of the table being longer than legs 3 at the opposite end, so that the end of the said table will be elevated above the other.

The table 1 comprises the base l, side walls 5 and 6 and the end walls 7 and 8, suitably soldered together forming a water tight inclosure having an open top. The side wall 5 is provided with openings 9 and 10, which are disposed at the opposite ends of the table just above base 4:. Pipes 11 and 12 are soldered or otherwise secured to the wall 5 and register with openings 9 and 10. Arranged on the base 4 and extending transversely across the inclosure are the cooling tubes 13, comprising substantially angle-shaped members having top and side legs 14 and 15. dered to the base 4t and the top legs 14 are inclined downwardly and soldered to the side legs of the preceding members. The

The side legs 15 are solangle-shaped members are also soldered at .leg 22 of the receiving angle-shaped member which communicates with the tubes 13, so that a stream "of water may pass from the water supply source through pipe 11, into chamber 17 and from thence by gravity through the cooling tubes 13 to chamber 18.

The tops of the tubes 13 form a series of steps, which are inclined at an angle opposite to that of the frame, so that a liquid poured at the receiving end will by gravity seek the lower level of the receptacle, being retarded in its progress downward by the said steps. Pockets 23 are formed on the tops of said tubes, between the side legs 15 and the top legs 14, which are of sufficient depth to momentarily hold the liquid while in transit, so that the same will be thoroughly cooled during its trickling progress over the said tubes.

The cream receiving chamber 24 is provided at the upper end of the table and has its inner wall 25 slidably mounted in brackets 26, on the side walls 5 and 6, providing means for regulating the flow of cream through the cooler. The end wall 8 of the table, is provided with an opening 27, which is in alinement with the top leg 20 of the water outlet chamber 18, and a pipe 28, having its opening registering with said opening 27, serves to carry cool cream from the cooler.

It will be seen that a stream of cold water passing through the tube by gravity will serve to cool the cream which trickles over the inclined tops of the tubes, the travel of the cream being retarded in its progress through the lower end of the receptacle, so that sufficient time ensues to thoroughly chill the cream. The amount of cream admitted to the cooling tubes is regulated by the opening or closing of the opening between the slidable wall 25, and the top leg 19 of the chamber 17.

\Vhile I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having described my invention what I claim as new and desire to secure by Letters Patent is: 7

l. A coo-ling device comprising an inclined frame; a plurality of communicating cooling tubes in said frame, the upper walls of said tubes being inclined oppositely to the inclination of said frame providing a pocket on the upper side of each tube, substantially as described. I

2. A cooling device comprising an inclined frame; a series of communicating cooling devices in said frame, the first and last of said series of said tubes having their upper walls parallel with said inclined frame and the upper walls of the remaining intermediate tubes being inclined oppositely to the inclination of said frame providing pockets thereon, substantially as described. 3. A cooling device comprismg an 1I1-7 clined frame; a plurality of communicating tubes arranged in said frame having inclined upper walls, said walls being inclined in a direction opposite to that of the frame, and adapted for the passage of a cooling element therethrough and for the passage of an element to be cooled thereover; a receiving chamber arranged in said frame; and a slidable member disposed in said chamber, adapted for regulating the flow of the element to be cooled, substan tially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
